Helen Caldicott, a Lannan award-winning activist named by the Smithsonian Institute as one of the most influential women of the twentieth century, has worked tirelessly for a safe, sustainable, nuclear-free planet. On November 8, Helen Caldicott will join renowned journalist Bob Herbert to discuss our most urgent global challenges and themes from her new book, Loving This Planet.

Loving This Planet features environmentalists and leading activists from around the globe discussing the chief environmental and social issues of our time. Together with some of the most brilliant thinkers and inspiring advocates of our time who have contributed to the book, including Maude Barlow, Bill McKibben, Martin Sheen, Jonathan Schell and Arjun Makhijani, and many others, Caldicott—whom Meryl Streep has called “my inspiration to speak out”—scrutinizes our unsustainable dependence on nuclear energy and the absurdity of nuclear arms and seeks to raise awareness about other planetary issues, including deforestation, sea-level rise, privatization of water reserves, the power of grassroots movements and the ability of unionized labor to influence politicians.

Dr. Helen Caldicott is a co-founder of Physicians for Social Responsibility. She is the author of numerous books, including Nuclear Power Is Not the Answer (The New Press). She lives in Australia.

Bob Herbert is a distinguished senior fellow with Demos and a contributing editor at The American Prospect magazine. From 1993 to 2011, he was an op-ed columnist for the New York Times, writing a twice-weekly column about politics, urban affairs, and social trends. Mr. Herbert’s numerous awards include the American Society of Newspaper Editors Award, the David Nyhan Prize from the Shorenstein Center at Harvard University, the Meyer Berger Award, and the Ridenhour Courage Prize for the “fearless articulation of unpopular truths.
